How it Works

How to measure ring size online

Learn how to determine your ring size quickly and easily.

You will need to calibrate your screen. To do so, just place a credit card or driver's license on the screen as indicated and then drag sliders so that they fit the card. Establishing the width of the card is essenttial for the ring sizer to work accurately.

There are two methods of finding your ring size:

1. Use any ring that fits the finger you plan to wear your new ring on and place it over the circles. Match the ring to the circle that completely fills the inside of the ring without overlapping. The size written inside the matching circle is your ring size.

2. Use our virtual ruler to find your ring size. First, cut a thin strip of paper that can comfortably wrap around the base of the appropriate finger. Mark the spot on the paper where it completes a circle. Place the strip of paper against the ruler and match your size.
